AC87U..I can't access Ruttorent WebUI (Entware)

Asuswrt-Merlin 378.55

I can't access Ruttorent WebUI from LAN (192.168.1.1:81/ruttorent) or WAN (myown.no-ip.biz:81/ruttorent)

I installed entware using the easy install script (entware-setup.sh) and Rtorrent using the easy install method:

https://www.hqt.ro/rutorrent-on-asuswrt-router-through-entware/

I see this method is labeled as "Mips only" but i saw some people using it also for ARM Asuswrt routers.

Rtorrent is already running:
